"WASHING MACHINE.

Application filed December To all whom it may concern:

Be it known that I, JOHN P. Moos, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

My invention relates to clothes washing machines, particularly to the rotatable cylin- 19 der type, and in general the object of the in vention is to produce a simplified, lighter, more durable, and more efiicient cylinder structure.

Cylinders have heretofore been constructed entirely of wood, comprising usually end walls formed of pieces of board cleated together, and slats nailed to and around the periphery of the end walls, with the cylinder supporting fittings bolted or screwed against the outside of the end walls. With this construction the slat fittings loosen after a while and the wood also absorbs so much moisture that the weight of the structure is greatly increased. All metal cylinders have also been used but these can become easily dented or bent, and in these structures the supporting fittings are also secured to the end walls by screws or rivets. Combination wood and metal cylinders have also been attempted but the slats have been secured by means of bolts and the supporting fittings are separate members secured by bolting or riveting to the end walls.

By my invention I overcome all the disadvantages of such prior structures, my construction comprising light end walls or disks preferably of aluminum, with wooden slats and lifter boards extending between the disks. Retaining sockets are provided on the end disks for the ends ofthe slats and retaining lugs are provided for the lifter boards so that no nails or screws are necessary. Furthermore the cylinder supporting fittings are cast integral with the aluminum end walls and by slight changes in the pat terns for the end walls the cylinder can readily be made adaptable for the different styles of washing machines now on the market. All wood parts are treated with water-resisting material and the structure is very much lighter than the structures of the prior art and has much greater strength, durability and eih'ciency.

On the accompanying drawing my im- 1, 1922. Serial No. 604,179.

proved construction and arrangement is clearly illustrated. On the drawing.

Fig. 2 is an end view thereof,

Fig. 3 is an enlarged end viewv with part 6 of one end wall'removed,

Fig. 4 is an enlarged transverse sectional view of part of thecylinder showing the cooperation of the cover with the cylinder body, Fig. 5 is a sectional view onplane 5-5, Fig. 4, and 7 Fig. 6 is an end view of a section of the cylinder showing the application of the cover to the cylinder body. 7

The end disks 10 and 11 are comparatively thin and each is in the form of an integral casting of some light material such as aluminum. The disks are identical except as to the supporting fittings thereon, the disk. 10 being shown provided with a trunnion pin 12 cast integral therewith and the disk 11- being shown with the rectangular socket 13 cast integral therewith. By slightly changing the patterns for the disks the required supporting extensions for the different styles of machines canbe readily provided. Each disk has a peripheral inwardly extending retaining flange 14:, and radially inwardly of such flange and concentric therewith is the annular retaining flange 15. Between these outer and inner flanges are received the ends of the slats 16, and to properly space the slats circumferentially to provide water passageways w therebetween spacing lugs 17 extend radially inwardly from the flanges 1a. The slats are concave on their inner sides so as to provide good rubbing surfaces.

Lifter or bathe boards 18 extend between the disks and are disposed in radial planes,

lugs 19 and. 20 extending from the flanges 15 receiving the boards at their outer cor-' ners to hold them against displacement. These boards serve also as a means for properly spacing the end disks and for drawing them together to rigidly receive the ends of the slats. The ends of the boards at their inner edges are received by hook bolts 21 which lie in grooves .22 provided in the boards and have the hook ends 23 extended into the holes 24 provided inthe boards, the ends of the screws extending out through suitable openings 25 in the end disks and being there engaged by the nuts 26. hen the nuts are tightened the end disks; are drawn up against the ends of the boards to form the rigid cylinder structure, and the slats will then be rigidly locked at their ends between the flanges 14 and 15 and the spacing and retaining lugs 17. The bolts cooperate also with the lugs 19 and 20 to hold the lifter boards securely in position. Assembly can be readily accomplished by first applying the nuts only loosely on the bolts and then springing the slats into'place with their ends in their respective retaining spaces, the slats being sufficiently thin and elastic, the this purpose. Then when the nuts are drawn tight the wood parts and metal ends are rigidly locked in proper relative position.

I have shown four lifter boards spaced degrees apart, and between two adjacent boards the end walls have the shallow peripheral notches 27 for accommodating the end walls of the cover structure,"these notches being about cover end walls 28 are identical and fill in these notches when the cover is applied, each cover end having a flange 29 for engaging against the inner side of the respective end wall of the cylinder body, so that the cover when applied will be preventedfrom being longitudinally displaced. Each cover end wall has outer and inner retaining flanges 30 and 31 which form continuations of the flanges 1d and 15 of the body part when the cover is applied, the spacer lugs'32 cooperating with the flanges to form retaining spaces for the ends of the slats 33 for the cover structure. To properly space the cover end walls apart the baffle or lifter bars 3d are provided which at their ends abut against the flanges 29 and 31 and are held in place by means of screws 35 applied thru the flanges 29.

At one end the flanges 29 are extended to provide abutment shoulders 36 for engaging under the respective ends of the retaining flanges 15 when the cover is applied, such engagement locking the cover structure at one end to the cylinder body. Suitable looking mechanism can be provided for the other end of the cover part end walls. As shown hooks 37 are pivoted on the cylinderbodycnd walls for engaging with pins 38 extending from the cover part as clearly shown in Fig. When it is desired to remove the cover the locks are opened and the cover is tilted sufficiently to disengage the shoulders 36 from the flanges 15, as shown in Figs. 4 and 6.

I preferably treat the wood parts of the cylinder to make them impervious to water. Increase in weight will therefore be prevented as the water cannot soak in. My improved structure is at least thirty-three per cent lighter than the all wood cylinders and this means that less power will be required 90.de-grees in extent. The two for driving the: cylinder and there will be 7 less strain particularly duringre-Yersing at the cylinder. The end disks are in themselves very light and as the slats can be sprung into place and securedibetween the ends without the use of nails or other special meta-l devices the weight is kept down to a minimum, and there w'll be no devices which could work loose. T cylinder will therefore be always rigid and properly balanced and consequently easily driven.

Having described my invention I claim as follows:

1. In a cylinder for washing niachines, tl c combination of metallic end plates, lifter boards extending between and rigidly secured to said end plates, said end plates having outer and inner annular flanges near their periphery, spacing lugs within said flanges forming receiving pockets therewith, 'and slats engaging at their ends in said receiving pockets to form the circumferential wall of said cylinder, said receiving pockets serving as the sole means for locking said slats against the longitudinal and circumferential displacement.

2. In a cylinder for washing machines, the combination of end walls in the form of thin metallic disks, inner and outer concentric flangesextending inwardly on the inner sides of said disks near the periphery thereof, "lifter boards extending between said disks inwardly of said flanges and rigidly secured at their ends to. said disks, spacer lugs within said flanges forming seating pockets therewith, and slats engaging at their ends in said receiving pockets to form the circumferential wall of said cylinder, said pockets forming the sole means for locking said slats against longitudinal and circumferential displacement.

3. In a cylinder for washing machines, the combination of end walls in the form of thin metallic disks, concentric annular flanges on the oppositely facing sides of said disks forming annular receiving spaces, lugs subdividing said spaces into pockets, slats engaging at their ends in said pockets, and means rigidly connecting said end walls together to receive said slats in said pockets, said pockets serving as the sole means for locking said slats against longitudinal and transverse displacement.

4. In a cylinder for washing machines, the combination of end walls, lifter boards extending between said end walls, abutments on said end walls for engaging with the outer ends of said boards to hold them against displacement, hook bolts engaging with the inner ends of said boards and secured to said end walls to hold the inner end of said boards against displacement, and slats interposed between said end walls to form the circumferential wall of said cylinder.
